Hi,

FYI... using diskpart and a drive goes offline it chooses or uses the device before it....without warning you

I mistakenly *thank you diskpart" "cleaned" a 250gb external drive. A sd card driver letter after the got popped out.. diskpart was configured to clean that drive but picked up the drive before ...

I have tried the following TestDisk(linux and windows),gparted, gnome disk and Minitool Partition Recovery V7.5...

Initially, Minitool found the 220GB of files so I didn't use it. The I tried various tools then ran it again and it only found 120GB of files...

Unfortunately the filesystem/partition had 2 ~30GB linux filesystems (raspberry pi) images had the tools (mainly gparted/gpart) mistakenly found those..

I have tried to attach the log files from TestDisk and minitool...

I suspect that the data is mostly gone now... but I was hoping it could be used to "enhance" testdisk because mintool still finds files and linux still finds the partition (or 2 of them being the same)..

Te following are some datapoints:

- exFAT filesystem on Samsung T3 external SSD 250GB, exFAT support might be part of the problem
- Linux reports 2 fat partitions but with the same info same size etc.. so that is probably messing up things
- other error messages are:
- Partition sector doesn't have the endmark 0xAA55,Invalid FAT boot sector (TestDisk messages)
- fsck.fat logical sector size is zero

This forum software is not allowing me to attached the logfiles.. invalid file type (extensions none, .txt, .log)

Help... Please and thank you...!!!!!

Frank

Please copy and paste the testdisk.log file content
